According to the State Council earthquake relief headquarters of the report of the estimates, as of June 19, 2008 earthquake damaged houses in the total amount of 24.343 million, total collapse of damaged housing 6.945 million, resulting in total no less than 500 million tons of construction waste, much Building Construction in China each year far exceeds the sum of construction waste generated.
Which waste brick, waste concrete, waste wood, scrap steel, scrap metal, etc. can be used as renewable resources.
Technology
According to statistics, the current construction waste comprehensive utilization of patented technologies in China has reached 172, mostly to achieve the transformation.
"Recycling of construction waste is technically feasible, and is mature." Sichuan Institute of Building Materials Industry experts say.
Ministry of Housing and Urban research report, earthquake construction waste in the city of 17 million tons of Mianzhu, Shifang city of 6.3 million tons, Dujiangyan city of 26 million tons.
"Using waste concrete and masonry waste can produce a certain intensity level of recycled concrete, recycled mortar, wall panels, floor tiles and other building materials. Add curing type material, can also be used for laying the road embankment." Xiao Professor of Civil Engineering, Tongji Zhuang Jian said. In addition, the residue can be used for road construction, waste wood can be recycled as wood boards, waste asphalt pavement directly in accordance with an appropriate proportion of recycled asphalt for concrete, steel scrap can be processed directly reused or recycled.
Under the existing technology, not only clean and renewable energy can be recycled building materials, and better quality. Recycled brick as the main material of construction waste, a small amount of fly ash, with addition of cement and other cement matrix, compared with 45% lighter than solid clay brick, the building can significantly reduce weight, reduce the total project cost. Compared with the traditional brick, insulation, seismic, seepage and other properties are also improved significantly.
Building materials for the production of renewable energy enterprises, technology is no longer difficult to cross the threshold.
Cost
To develop renewable energy materials, the cost is on the second threshold.
"Of course a great help." Speaking of the cost of financing in mid-October 2008 the implementation of the Ministry of Finance "Financial subsidies for renewable energy-saving building materials Interim Measures" of the bandits all have is undoubtedly a major positive. "A month ago we had reported on the material, it is waiting for approval."
At present, the bandit has invested more than 1,000 all-yuan, he said, state loans and special funds with the support of the international financial crisis on the financing of enterprises did not cause difficulties.
In addition to financing costs and the cost of production. "Our production costs mainly in construction waste debris filtering, sorting, crushing and other sectors." Local government building materials companies in renewable energy policy support to address the bandits all have in land prices and construction costs of waste transportation worries.
All have brick factory located in the Kou Mianzhu, relevant government departments to give the best prices of productive land, and to oversee the owners of buildings collapsed and demolition waste delivered to the brick production free of charge on site, piling up at the designated locations.
The contrast of traditional shale brick, the town of Beichuan thunders the local brick factory operators Wu Youxu have forget such a statement: an annual output of 30 million regeneration of a brick factory, invested two million yuan, the biggest cost is the brick machine, the new device is added crusher, one in 30 million. The same shale brick production, the investment is 600 million. In addition, each block of shale brick converted into standard coal consumption of energy is more than 100 grams, and construction waste brick is 30 grams. The same capacity, the area of shale brick at least 50 acres, construction waste brick factories accounted for 10 acres of land sufficient.
In contrast, the cost of construction waste as recycled brick obvious advantages.
Market
In Sichuan, renewable energy marketing materials can be expected.
While the whole bandit just some brick production, the construction units have 45 to find the door, booked more than 1,000 10 000 recycled brick. His market confidence, the support from the government, on the optimistic post-disaster reconstruction market demand and product quality excellent.
Mianzhu City Planning and Construction Bureau under construction development projects, municipal projects, will give priority to design and promote the use of construction waste products, measures, and construction units as possible to encourage the use of such use of construction waste produced building materials.
Currently, only one place Mianzhu the restoration and reconstruction work necessary to build various types of housing five thousand sets of brick demand reached 3.5 billion standard bricks. Shale brick are so tight, the market prices have soared to 0.55 yuan per piece, have to queue up and wait two years to supply.
"Our product quality has reached the national industry standard, but brick no. And we will certainly be lower than the market price of red brick on the price, probably more so in the three hair." Bandits all have said.
Mainly for the rural market for the brick factory, "to promote it a bit difficult." Brick factory in Mianyang operators admitted. To prove the quality of their office room with a pilot, the results show identification, publicity through various channels, to dispel the concerns of farmers. Meanwhile, Sichuan Province, local standards are being developed for the product to determine the appropriate parameters, to better ensure the quality, protect the people's interests.
